Tomasello, Chapter 4

[Weightshift]

I'm finding the whole Tomasello videos very instructive. In Chapter 4 he discusses and demonstrates vertical, horizontal and angled hinging and he shows that these three motions are caused by manipulations of the clubface (guided by the back of the left hand, or front of the right hand) from impact to finish.

He then goes on to demonstrate that these three ball flights are caused by down the line, inside out and outside in swings.

So which is it? ..or is hand manipulation, or clubhead path manipulation wrt the stance line, just alternate solutions?

Thanks,
Alan
